摘要
以试验用线性涡流制动电磁铁为研究对象,从能量转化角度推导涡流制动力的计算式,建立简化的二维静态电磁场模型,并借助于有限元分析软件进行计算,得出励磁电流、工作气隙和运动速度等参数对涡流电磁铁制动力的影响,为涡流制动电磁铁的设计提供参考。
This article takes a linear eddy-current brake magnet used in test for the research object. It derives equations of eddy current braking force from energy conversion. It builds a simplyfied model of 2-D static electro-magnetic field and calculates the braking forces by means of finite element analysis software, and also analyzes effects on braking characteristics produced by current, air gap and speed. It could provide some references for design of eddy current brake magnet.
